Covariance of Kinetic Parameter Estimators Based on Time Activity Curve Reconstructions: Preliminary Study on 1D Dynamic Imaging
We provide approximate expressions for the covariance matrix of kinetic parameter estimators based on time activity curve (TAC) reconstructions when TACs are modeled as a linear c...

Time delay estimation in the time-frequency domain based on a line detection approach
The estimation of the time delay of arrival (TDOA) or the direction of arrival (DOA) has been an important research topic within the last few decades. In several applications, e.g...

Robust line detection using a weighted MSE estimator
In this paper we introduce a novel line detection algorithm based on a weighted minimum mean square error (MSE) formulation. This algorithm has been developed to enable an autonom...
